Description
Technical field
The present invention relates to aviation aircraft field of mechanisms, more particularly to a kind of machine general to different size Inspection Aircraft Wheels
Wheel tears tire or dress device of tyre open.
Background technology
Fixing device of the aviation from compression type tire with wheel is generally blocking piece type structure, in use the restoring force of tire
Wheel rim is promoted axially to move laterally along wheel hub, wheel rim is stuck in fixed position by the fixture block installed on wheel hub, makes wheel rim and wheel
Hub cannot depart from, and dismantling this kind of tire needs to apply tire end face on uniform downward force extruding tire, takes out the card on wheel hub
Block, can just be such that wheel rim departs from wheel hub, so as to remove tire.Aviation tubeless vacuum tire needs vacuum wheel with the sealing of wheel
Gases at high pressure are filled with inside tire, and gas extrusion tire is made tire be brought into close contact with wheel hub and could not make leakage of tyre, vacuum tire
After life-time service, together with tire is adhered to wheel hub binding face, the replacing of tire is such as carried out, need to apply uniform to tire end face
Downward force, tire and wheel hub binding face can just departed from.As compression type tire restoring force is larger, vacuum tire is glued with wheel hub
Lian Li is also very big, and dismounting both tires needs to carry out on special instrument.
What domestic this two kinds of tires and dismounting multipair different wheel, the tire greatly of wheel had a special size tears device of tyre open.
The parts difference that the various model features of device of tyre are different, adjust in the application is torn open due to special, needs professional to be grasped
Make, it is more complicated.
The dismounting speed of Inspection Aircraft Wheels and tire directly influences wheel and tire disassembly efficiency aboard and outfield
Comprehensive guarantor's maintenance time.As airport needs the aircraft species safeguarded a lot, the wheel of correspondence aircraft, tyre model are also different.Ground
Diligent personnel are frequently necessary in a short period of time different model wheel, tire be carried out checking, keep in repair, have longevity part to change, maintain
Deng, many times need to carry out tire, wheel fast assembling-disassembling on outfield, airstrip or runway, ensure aircraft overshoot, often
Tire is torn in secondary lookup, carrying Multiple Type open or dress device of tyre is very inconvenient.
